Abstract
A novel cassette structure technique for enabling simultaneous burn-in of pluralities of LEDs plugged into the cassettes, and then, with the cassettes mounted within a light integrating sphere system, separately measuring the spectral flux emitted by each successive individual LED plugged into the cassette to determine optical and electrical characteristics of each LED separately from the others.
